Frequently Asked Questions

These questions can also be found in Backer's help file, section Support And Inquiries, topic Frequently Asked Questions (FAQ).

Clicking on a question will take you to the answer.


How do I suppress the preview for unattended runs?
Uncheck Options | General | Checks | Show preview.

Are there maximum file sizes and numbers Backer can handle?
Backer can handle file sizes greater than 4 GB almost everywhere. Exception: files in Zip archives and the archives themselves, which are both limited to 2 GB, and FTP, which is limited to 4 GB. Backer can search unlimited quantities of data and copy unlimited numbers of files. Extremely many files found may eat up your computer's free memory, but you'd need over a million of them to even notice that on a 512 MB system. If Backer shows errors, size or number restrictions are most probably not the cause.

Does Backer provide the three basic types of backups: full, incremental, differential?
Yes, via the age filters under Options | General | Age.


Why can't I see any network drives?
Backer can browse your network automatically, but this option is off by default because browsing could take a long time on a larger network. You can browse the network by hand by (1) right-clicking on a closed drive list and selecting Browse network, (2) selecting the last entry of a drive list which always is Browse network, or (3) enter a network drive directly. Backer remembers network drives for future access. For details see Options | General | Miscellaneous in the Program Control section and Accessing Network Drives in the What You Need To Know section in Backer's help file.

Can I back up from more than 1 drive in one run?
No. The limitation of 1 drive in source and destination has the technical reason that files must be related unambiguously in both directions. Even in a one-directional operation like a backup, Backer must check both directions to detect orphans. Create a separate profile for each drive, and then create a batch file from these profiles to run them one after the other.

Can I select individual file types for each directory in the source?
No. Selected file types pertain to all directories at the same time. There is no technical reason, we just did not want to clutter the user interface. Create a separate profile for each combination of directory and file type, and then create a batch file from these profiles to run them one after the other.


How do I create a batch file?
Via File | New.

When synchronizing Outlook Backer reports that the .pst file is used by another process. Must I close Outlook first, or is there another solution?
We recommend to close Outlook. You will find general information on the problem of open files under Open Files in the Miscellaneous section in Backer's help file.

How do I modify profiles or batch files that due to automation options start and exit automatically?
Press Shift on program start to prevent the automatic run.


How can I set the scheduler for each profile in a batch file individually?
Batch files are for running profiles immediately one after the other. If you need individual start times, start each profile with a Backer copy of its own.

Does Backer transfer the permissions under NTFS?
Yes. For files check Options | General | Miscellaneous | Transfer file permissions. For directories check Options | General | Directories | Transfer directory properties. Note the limitations listed under Attributes, Permissions, Owner in the Miscellaneous section in Backer's help file.

How do I make the destination an exact copy of the source?
See How to Make the Destination an Exact Copy of the Source in the Miscellaneous section in Backer's help file.


What can be done against mysterious errors like "Error 183 - Cannot create a file when that file already exists."?
Backer has special features for error prevention and handling under Options | General | Problems. Selecting Verify errors and On error retry x times often makes the error vanish.

Does Backer have difficulties with very long file names?
Not Backer, but Windows. The maximum length of a path, including drive and directories, is approx. 260 characters. Windows shortens names accordingly or prevents the entry of additional characters, respectively. But Windows can be tricked by access via a UNC name instead of a drive letter. A path can get longer than 260 characters this way. Windows will then issue nonsense messages like "A file name cannot contain any of the following characters: ...". In contrast, Backer will issue the correct "Error 206 - Path too long.".

Does Backer get confused by similar short file names for MS-DOS?
Not Backer, but Windows. This is one of the nastiest bugs in Windows. The automatically assigned 8.3 file names of identical long file names in different directories are not necessarily identical. Conversely, identical 8.3 file names in different directories do not always belong to identical long file names. Unfortunately, this puzzles Windows's internal search functions - there is nothing Backer can do to straighten this out.


Can Backer work with tape drives?
No. Tapes are sequential media and cannot delete or add files in the middle. That is why they come with special software. And they do not appear as drive letters in Explorer, thus they are not available system-wide.

Some windows are larger than the whole screen, or window texts do not fit properly.
Scaling is a complex matter. Please see the manual, we've added a new topic named Scaling in the Miscellaneous section.

The progress indicator runs irregularly - first quickly, then crawlingly.
Windows uses a cache. This means data are not written to the disk immediately but temporarily only to memory - which is fast. In a system breather the actual writing takes place. Programs cannot detect a cache because the operating system's feedback is identical with or without cache. The big disadvantage of a cache: If you simply switch off your computer instead of shutting it down properly, a write process may not yet have finished and you might lose data.

How can I speed up copying?
Experiment with the copy buffer under Options | General | Miscellaneous.
